User Manual

These panels require 12 or 13 digital pins (6 bit data, 6 or 7 bit control) and a good 5V power supply, at least a couple

amps per panel. We suggest our 2A (or larger) regulated 5V adapters and either a terminal block DC jack, or solder a

jack from our DC extension cord. Please read the rest of our tutorial for more details!

Keep in mind that these displays are normally designed to be driven by FPGAs or other high speed processors; they

do not have built in PWM control of any kind. Instead, you're supposed to redraw the screen over and over to

'manually' PWM the whole thing. On a 16 MHz Arduino Uno, we managed to squeeze 12-bit color (4096 colors) but this

display would really shine if driven by an FPGA, CPLD, Propeller, XMOS or other high speed multi-processor controller.

Of course, we wouldn't leave you with a datasheet and a "good luck!" We have a full wiring diagrams and working

Arduino library code with examples from drawing pixels, lines, rectangles, circles and text. You'll get your color blasting

within the hour! On an Arduino Uno or Mega, you'll need 12 digital pins, and about 800 bytes of RAM to hold the 12-bit

color image (double that for the 32x32 matrix).

The library works with a LIMITED NUMBER of boards: Arduino Uno, Mega, Zero, Adafruit Metro M0 and Metro

M4. Other boards (such as the Arduino Leonardo) ARE NOT SUPPORTED.
